JAMES WVILSON, OF COLUMBIA, MISSOURI.

BLIND-STOP.

SPECIFICATION forming part of Letters Patent No. 474,891, dated May 17, 1892.

Application filed September 21, 1891. Serial No. 406,385. (No model.)

State of Missouri, have invented certain new and useful Improvements in Looks for Blind- Slat Rods, of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

My invention relates to improvements in locks for blind-slat rods; and it consists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

In the drawings, Figure 1 is a vertical section of a window-blind with parts broken away, showing my invention applied thereto. Fig. 2 is a similar view, but showing the slats open. Fig. Sis a side elevation of myinvention. Fig. 4. is a perspective view of the sliding catch or look which I employin carrying out my invention; and Fig. 5 is a front eleva- I tion of my invention, especially showing the parts of the blind to which the same is attached.

I will describe the use and operation of my invention in connection with a mechanical description thereof.

Referring to the drawings,1 indicates a series of blind-slats, and '2 the slat-operating rod,which is secured to the same in anysuitbio and mechanical manner.

piece of the window-blind. Secured to said cross-piece in any suitable and mechanical manner are two right-angular brackets or braces 5, the same being provided with perforated ears 4. Pivotally interposed bet-ween said perforated ears 4 is a bar 6, the same being provided with a series of perforations 7 out of alignment, or, that is, of unequal distances from the edge of said bar.

8 indicates a plate, the same being pro-' vided with perforated ears 9. Said plate 8 is 5 indicates the transverse bottom crossing lug 11, the same adapted to fit in the perforation '7. The normal position of the bar 6 is between the plate 8 and the pivoted catch or look 10, as illustrated in Figs. 2 and 5. may be noted in this connection that the plate 8 is rigidly secured to the operating-rod 2 and moves vertically with the same-that is, in the operation of opening and closing the slats 1. The plate 8 is provided with a perforation 12, in which the end of the lug 11 may fit.

From the above description it can be readily perceived that the rod 2 may be held in any desired position (thus holding the slats 1 in any desired adjustment) by simply inserting the lug 11 in any of the perforations 7. It may be noted, also, that the space between the perforated ears 9 is sufficiently large to permit a rocking motion of the plate 8 and pivoted catch 10 as the same is moved upwardly and downwardly on the bars 6. (For illustration see Figs. 1 and 2.)

Having fully described my invention, what I claim -is' g 1. A blind-stop consisting of right-angular pieces or braces 4, secured to the lower crosspiece of the blind, a bar 6, pivotally mounted at its lowerend between the same, perforations 7, formed in the said bar and out of alignment with the edge of the bar, and a plate adapted to be attached to the slat-open ating rod, having mounted thereon a pivoted catch or look 10'for engagement with the said perforations, substantially asset forth.

2. 'As a new article of manufacture, a lock for blind-slat rods, consisting of right-angular braces 4, providedwith perforated ears 5, a bar 6, provided with a series of perforations 7, out of alignment, pivotally mounted between said ears, a plate 8, provided with perforated ears 9 and with a perforation 12, and a pivoted catch or lock 10, provided with a lug 11, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
